OpenVPN with Root - Updated 8/19

[vossco32]

I'm also having issues getting OpenVPN to work on the official release ROM.

Getting FATAL: Cannot allocate TUN/TAP dev dynamically on the final 2.2 release.

This is the same error I am getting. If you check the logs it is not loading the tun module because it thinks it is for a different kernel. It is actually the same kernel just with a difference version string. Old kernel string 2.6.32.15-g5e1ad8b new kernel string 2.6.32.15-gb7b01d1.

I installed Kings kernel that has tun.ko compiled in. I can now connect but back to where I can't ping anything, unless I do a "ifconfig tap0.....". Damn, why is this hard to get working lol

I used a hexeditor to change the first (and only, I think) instance of "2.6.32.15-g5e1ad8b" in tun.ko to "2.6.32.15-gb7b01d1" and it loaded fine, connects fine, everything AOK. No recompile needed. I don't know if that would have worked had the strings been different lengths.

Does this run with CM6 later versions such as 6.0.2?
I saw that the CM6 kernel didn't have tun in earlier versions.

Hi! I am new to opnvpn on mobile. I have HTC Desire with LeeDroid 2.2f ROM and I'm rooted. I managed to use and open openvpn installer. It seems working from logcat. Also, I am using openvpn client on Windows with a user account. The problem is that from where can I get the .cert .ovpn etc. files. Or how can I create them manually? Any help appreciated.

"Make sure you copy your config file and any relevant keys to a folder"

I'm a noob and trying to install OpenVPN on my Inc. I am using HMA Pro on my W7 computer, but where do I find the Config files and relevant keys that you mention in the quote above? I have no clue.

Would appreciate some direction on this!

Easy way - OpenVPN on rooted/S_OFF Incredible with BusyBox installed:

This is by far the easiest way to set up OpenVPN. Make sure you copy your config file and any relevant keys to a folder on your sdcard. First, you need to know where BusyBox is installed, and if you already have the tun.ko module. For BusyBox, for most Roms based off the 2.2 8/1 leak, the location is /system/xbin. An easy way to check on your phone:

adb shell
find / -iname "iptunnel"

The path containing the file is where BusyBox is installed. If you don't have it installed, you can follow the instructions at the bottom of this post to install it.

The tun.ko module depends on your kernel. With the hydra 2.2 kernels, the location is /system/lib/modules/tun.ko . Easy way to check:

adb shell
find / -iname "tun.ko"

If you do not have tun.ko on your system, then you can download it for 2.2 (tun.zip) or 2.1 (inside openvpn.zip) attached to this post.

Next, download the following two apps from the Android Market:


OpenVPN Installer
OpenVPN Settings


Next, run OpenVPN installer, click install, give it an install path (I prefer /system/xbin), and give it the path to BusyBox.

Finally, run OpenVPN Settings. Go to Menu -> Advanced, make sure "Load tun kernel module" is checked.

Click on "TUN module settings"
Change "Load module using" to insmod
Change "Path to tun module" to... the path to your tun.ko file. Click back.
Update "Path to configurations" and "Path to openvpn binary".

That should be it!

--

I followed all these instructions, and openVPN has a checkmark next to it, but when I click on any of the servers it just says "superuser privileges has been granted," but won't actually check the server. So nothing happens. I'm using Virtuous 2.2. I used the Tun.ko file attached to this post.

What am I doing wrong and how can I fix it?

well, i played also with openvpn ...
but now on my new device galaxy 9000, the problems are ongoing ...

Mon Feb 7 22:33:03 2011 Options error: Unrecognized option or missing parameter(s) in [PUSH-OPTIONS]:4: route (2.1.1)

this would mean, that the busybox doesn'T support the ifconfig/route commands...

any idea ?
info:
device: galaxy i9000
kernel: 2.6.32.9 (speedmod with tun configured in kernel)
firmware 2.2.1 (build darky's rom 9.2)
busybox: BusyBox v1.17.3 (2010-10-18 13:41:40 BST) multi-call binary.
(all links for ifconfig + route made to the busybox in /system/bin + /system/xbin/ +system/xbin/bb

any idea ?
